This tank will remove floating materials, plastics, larger objects etc., which will otherwise clog the pumps.
Altido offers a fresh approach to the drainage industry. We provide a professional and reliable service that is also cost effective. Our sewage treatment consultants have over 30 years experience to call upon and using the latest technologies we ensure disruption is kept to a minimum.
The controlled process flow from sewage collection tank is taken into inlet launder of this tank. Floating type media is introduced within the treatment tank. This media is made up of special grade plastic of special density. In course of the treatment a bio-film develop on the elements.The FABR within the reactor is provided with the help of diffuser placed at the bottom of the reactor. The thin bio-film developed on the elements enable the bacteria to act upon the biodegradable matter in the water and reduce the BOD content while, certain amount of COD is also removed. The overflow from the outlet launder is taken into flash mixer under gravity.
From the FABR tank the sewage will lead into secondary settler in which settling of microbial floccules takes place at bottom of the tank as sludge. The supernatant from top will over flow through launders into the Semi Treated Water Tank under gravity.
The excess bio-sludge from Secondary settler will be taken into this tank. The degraded sludge removed after 5-6 months from here can be used as Manure.
The treated water from Secondary Settler will be collected into this tank. This treated water gets pumped into tertiary filters.
After Secondary treatment, the treated water will be given the tertiary treatment. The tertiary treatment consists of two phases.
Our chemical free bacteria and corrosion control process also helps protect assets and improve productivity by effectively combatting scaling, corrosion, and bio-fouling, while eliminating costly biocides and reducing scale inhibitors needed for corrosion control.
The complete filtration operation comprises of two phases. Filtration and cleaning or regeneration (Commonly called as backwashing). The filtration phase in which particulate matters are removed and accomplished by passing the waste water to the filter through a filter bed composed of granular materials. Within the granular medium filter bed the removal of suspended solids has accomplished by a complex process involving one or more removal mechanism such as training, interception, impaction, sedimentation, flocculation and adsorption. The end of filter runs (filtration phase) is reached when the suspended solids in the treated water start to increase beyond an acceptable level or within a limiting head loss occurs across the filter bed. Once either of this condition is reached the filter must be cleaned (backwashed) to remove the material (suspended solids) that has accumulated within through the granular filter bed. Usually this is done by reversing the flow within through the filters. The sufficient flow of washed water is apply until the granular filtering media is fluidized (expanded). The material that has accumulated with a bed is then washed away.
The pressure adsorption phase is a final polishing step in the removal of all organic matter. This is also required for removal of color, odour etc. from the treated water.
The treated water from secondary treatment may consist of some pathogenic micro organisms to get the reusable water, it should be pathogen/germ free and should have been contacted with the oxidant/disinfectant chemical/UV radiation more enough to remove these species. Here the specific range of UV spectrum disinfects the semi treated water. This water is then collected into Semi treated water tank.
