Description :The proposed plant incorporates Pre-treatment, Chemical treatment, Disinfection and Sand filtration system for recycling of treated effluent and sludge handling units as follows:- Contd...

(A) Pre-Treatment & Pumping Station:- The proposed pre-filtration is based on a solid liquid separation unit using a screen technology, the unit is a stand alone compact plant to pre-treat effluent entering the chemical plant at flow rates up to 5 KLD. The process is completed through two steps as below: - (a) Fine screening (10mm opening):- it is a completely enclosed system for an external above ground or below ground installation that :- (i) Screens solids from the waste water. (ii) Lifts the screenings above the wastewater level and simultaneous washes the screenings. (iii) De-waters the screenings which are discharged into conveniently trash can. Design features:- (i) Screen Mesh:- 10-16mm (ii) Stainless steel housing (iii) Shaft-less spiral screw made of stainless steel (iv) Pre-fabricated and limited civil work required as per OEM design. (b) Equalization tank:- The effluent is mainly collected from different sources and forward to Equalization tank. It is a continue process, the plant work to average 1000 Liter per hour. The ETP should be designed on the basis of Physio-chemical along with tertiary plant as per OEM. Contd...

(B) Secondary Treatment :- The effluent will collect in RCC Collection tank of M-30 design mix, here the effluent mix-up by air blower and pump to the next process. The effluent now comes into CRT/Flash Mixer Tank where a specific type of Chemical used for chemical precipitations. Now the effluent is passed into primary settling tank to settle down in the hopper of bottom tank. It is complteted in two steps as below: (i) CRT/Flash Mixer (ii) Primary Tube Settler (C) Tertiary Treatment:- (i) Sand filtration system (ii) Activated Carbon Filter Tertiary Treatment Unit includes the following:- (i) Effluent collection tank-1 Nos (ii) Filter feed pump-1 Nos (iii) Sand filter vessels, of FRP, complete with sand and Gravel media- 1 Nos (iv) Activated carbon filter vessels, of FRP with activated carbon media-01 Nos.
