Water Filtration Fundamentals

Numerous water filter technological innovations extend constrained biological sources with regard to drinking standard water the quality of water fed into our homes and industries has declined over many years. This specific decrease in water quality comes via the excessive demand from customers on an already strained water source. Several concepts involving water filtration are employed within many purposes in order to increase the quality of the feed water.

Carbon Water Filters

The filtration of water through a carbon filter system is mainly utilised for final treatment and is recognised as having the best aesthetic quality correction. Activated carbon is very successful with lowering quantities of chlorine or various other halogens away from the water stream. The majority of carbon filters are established together with automated backwash controls designed to raise as well as clean the bed and also suppress organic growth. Carbon filters ought to be swapped occasionally to guarantee correct process performance. In the majority of instances, this approach will protect against any kind of bacterial development issues.

Neutralising Water Filters

Mainly used in the adjustment of Ph balance where acid water conditions are present. Acidic water can lead to damage of pipework, lead and copper which can leech into the water. These kinds of filters are usually implemented downward of the flow using an automatic backwash control head to help material solidifying. They may also be implemented upwards of the flow without the need for a control valve.


Coagulation is a two-step procedure extensively employed for filtration of colloidal as well as suspended matter throughout the water, which usually will be apparent in most instances. This type of matter when left to stand ill not settle to the bottom and wont pass through most types of other filters. The 2 step process firstly consists of adjusting the pH through chemicals initially before filtration can commence. With the introduction of a coagulant the particulate will bond together allowing it to be filtered. The best method for filtration of the coagulant will depend on system size and flow rates. At Industrial Water Equipment we will be able to best advise what filtration method would best suit your particular needs.

Screen Water Filters

Screen water filters are finished in either plastic, bronze, stainless steel or cast iron. This type of water filter is available with a variety of screen sizes ranging from 60 to 1,000, sizes relate to the tightness of the mesh weave and also the size of the particulate that the filter can eliminate. The majority of screen water filters possess a drain or blow-off ability in order to clear solids out of the filter, by making use of a straightforward ball valve or an electronic timer and solenoid valve. Screen filters tend to be employed in main water supply systems, wells and surface water systems in the function of removing waste debris. Screen water filters are capable of filtering fragments of pipe or iron, large particle debris, shells & sand particles. This particular form of water filtration is most effective at filtration of large material substances.

Oxidising Water Filters

Oxidation may well happen in a number of possibilities such as chemical substance treatment. The usage of oxidising water filters is popular for the purpose of wiping out the the majority of challenges found within well applications. Iron, manganese and hydrogen sulfide are regarded as some of the most typical issues with well water.

Another manner of oxidation treatment ion is actually ozone. Whenever oxygen is flushed via a chamber and charged with an electric current it turns into ozone. When used this kind of method is highly effective. Ozone treatment should be implemented in conjunction with a vented retention tank followed by filtration of the water.

Manganese greensand filters are frequently employed. This particular medium needs a regeneration cycle implementing a chemical substance potassium permanganate. They are typically intended to function along with a control valve with a regenerant draw functionality. Typically the potassium is added into a feeder dry. The feeders should have a control float alone with an automatic control valve to obtain the water required in order to break down the substance. This kind of technique has standard durations of regeneration, which usually involve a initial backwash. That will certainly support in the elimination of any kind of foreign matter or particles. Continuous feeds are typically used within industrial applications. This process is achieved by using a holding tank incorporating potassium permanganate and feeding the chemical into the stream prior to the filtration.

Clarifying Water Filters

Clarifying water filters widely made use of with regard to turbidity.The appropriate options of water filter design is based mostly on the flow rate. Each filter will require correct sizing to requirements for flow rates to be able to avoid seepage or blow-through coming from over-running the actual system. Be certain to have an understanding of servicing arrangements of every cartridge type as well as that appropriate water flow is obtainable in order to support the necessary backwash. Avoidable deficiencies frequently originate from system neglect or even incorrect flow-rate accessibility.
