Private Water Supply

Our experience in dealing with Private Water Systems means we have the knowledge to be able to offer solutions to what often can seem to be the most difficult of situations.
There are three main types of private water supply in the U.K. each offering a range of problems that require treatment. They are:

Wells – most wells are aquifier-fed where water is provided from a relatively shallow underground source.

Springs or streams – this type of system is usually the simplest and consists in the main of a protected collecting chamber into which feed water is diverted before being delivered to a storage tank within the property.

Boreholes – Boreholes extract water from deeper levels than other sources. Using a rigid tube of 4” or 6” reaching down to the supply and a submersible pump at the base, they can operate in depth in excess of 150 feet

Problems relating to low pH are easily resolved by installing a pH corrector.

 

Water from a private water supply is often acidic (less than pH 7) which means it causes pin-holing of copper pipe and hot water cylinders which frequently leads to copper leaching into the water causing discolouration (blue tinge / staining) of sanitary ware and blonde coloured hair.

Problems relating to low pH are easily resolved by installing a pH corrector. A pH corrector is a cost effective method of treating the water and works by slightly increasing the calcium and magnesium content of the water, however it does not alter the water's natural taste or take away healthy minerals.

This type of filter does not incorporate a back wash facility and the water passes down through the filters internal riser tube and comes up through the media, passing out of the filter head and into the system.

In order for us to be able to offer a guaranteed result we will require a water analysis, details of application and pipe sizes and/or flow rates.

Types of Iron

There are three main forms of iron and manganese. Other types are much rarer

  • Ferrous - This type of iron is often called "clear water iron" since it is not visible in poured water. It is found in water which contains no oxygen, such as water from deep wells or groundwater. Carbon dioxide reacts with iron in the ground to form water-soluble ferrous bicarbonate, which, in the water, produces ferrous ions (Fe++).
  • Ferric - Ferric iron is also known as "red water iron". This type of iron is basically ferrous iron which has been exposed to oxygen (oxidized), usually from the air. As carbon dioxide leave the water, oxygen combines with the iron to form ferric ions (Fe+++). These oxidized  particles are generally visible in poured water.
  • Bacterial Iron - Slime depositing in toilet tanks or fouling water filters and softeners is a good indication Iron showing in toilet bowlof the presence of bacterial iron. Better described as iron bio fouling, the iron bacteria problem is both complex and widespread. It attacks wells and water systems around the world in all sorts of aquifer environments, both contaminated and pristine. In some places, it causes great damage; in others, it is considered a minor nuisance. 



Treatment Methods for Iron Removal



Iron Bacteria


Iron bacteria can be controlled by periodic well chlorination or it can be treated in the building. The treatment involves the following: Chlorination, retention, filtration. Activated carbon is usually used as the filter material so the excess chlorine can also be removed.

Ferric Iron 

In theory, the elimination of ferric iron is simple - use a properly sized media filter to filter it from the water. In practice, however there may be other issues:

    Iron Reduction Unit
  • Some iron may be present in colloidal form. Unlike ferric iron, which will generally stick together to form large flakes, the tiny particles of colloidal iron do the opposite. Their large surface area and charge relative to their mass causes the individual particles to repel one another. As a result they will not coagulate. Their small size, then, makes them difficult to filter, and a coagulating agent is often required to obtain adequate filtration.
  • Most water containing ferric iron also contains ferrous iron. This can add complexity to the process, since some of the methods for removing ferrous iron will also remove ferric iron.

Crystal Right Media

A silica crystal media engineered for superior softening, neutralizing and filtering

Crystal-Right silica crystals are a natural choice for today's water conditioning systems. No other media does so much to condition problem water in a single pass.

Often called "zeolite" crystals, this media comes from a sodium aluminosilicate formula that is produced and processed by Mineral-Right using an exclusive technology. Through its unique crystalline structure, Crystal-Right™ provides superior removal of hardness, iron and manganese, while at the same time, raising pH levels of acidic water.

Unlike round, resin beads, Crystal-Right™ crystals provide better filtration, yet are thoroughly cleaned by backwashing faster than ordinary resins without loss of product. The irregular surface of zeolite crystals provides a far greater capacity for ion exchange than possible with smooth, round resin beads. In addition, Crystal-Right is impervious to chlorine – thus, an ideal media for use with our self-chlorinating, automated sanitizing systems, the Sanitizer™ Series.

How Aeration Systems for Water Treatment Work


Aeration is used in water treatment as a pre-treatment in the process of removing iron and hydrogen sulphide (rotten egg smell) from water. Air is a powerful oxidizer of both iron and hydrogen sulphide. It quickly converts irremovable ferrous iron to filterable ferric iron, and it reduces hydrogen sulphide to elemental sulphur, which is easily removed from water by a filter.

Air is a very fast oxidizer--considerably faster than chlorine.
Residential Aeration System Illustration
The illustration on the right is of a typical residential aeration system, showing one of the ways that air can be introduced into water to treat iron and hydrogen sulphide. It features a small air compressor and a special tank in which treatment takes place. The system above has an electrically controlled vent system to vent some of the hydrogen sulphide gas to the atmosphere, but especially to provide for a turnover of air in the tank.

The air pump delivers air into the tank and a pocket of compressed air forms in roughly the top third of the tank. As water enters the tank through the pipe at left, it hits a baffle (of the three pipes attached to the vent head, it's the short pipe on the left) and sprays down through the pocket of compressed air. The water is further aerated inside the tank before it leaves by way of the long tube (called a riser) which picks it up at the bottom of the tank and sends it out through the pipe at right. The mid-length tube in the centre is the vent tube. It controls the depth of the air pocket.

When the air pump is activated, the solenoid valve opens at the same time and an air/water mixture exits the tank via the middle tube and the drain line.

The pump and vent are controlled by the same electrical circuit so that when the pump is running, the vent is open and air is being exchanged. When the pump turns off, the vent closes and the compressed air pocket is maintained.

The electrical circuit that turns the pump/vent system off and on can be controlled in a variety of ways. The most common is by wiring them into the well's own pump circuit, so that the aeration system is activated when the well pump is running. Another way--and this is shown in the diagram--is with a specially designed control that monitors the pressure inside the aeration tank and activates the pump/vent according to aeration tank pressure. A third popular activation system is a flow switch, which turns the pump/vent system on when water is flowing to the home. 



The "Venturi" System
Venturi System
The venturi system uses no power. When the well's pump comes on in response to low pressure in the pressure tank, air is sucked into the main water line through the small venturi valve just before the pressure tank. The air is mixed with the water inside the aeration tank at right. Some of the air is vented to the atmosphere through the small vent valve on top of the aeration tank. After a short residence in the aeration tank, the aerated water continues to the next treatment stage via the water pipe at right.

Venturi systems are simple and relatively inexpensive, but they have the disadvantage of restricting water flow (the venturi itself pinches the water stream to create the vacuum needed to pull in air).
