The problem of small wastewater treatment plants has increased in recent times. Possibility has dominated necessity in the developments in this branch.
What is Sequential Batch Reactor?
These are the special form of activated sludge treatment. It is a type of treatment process in which the clarifiers are not required. In, this the waste water is treated in batch mode. Each of the batch mode is sequenced through a series of treatment stages.SBR has a small capacity upto 4 solenoid valves or pumps. Possibly, these valves or pumps get malfunctioned any time.
The present situation
There are firms which give an offer to furnish the small waste water treatment plant with an internet connection. The planned servicing and repair of the plants and its operating as well is getting more problems in recent years.
Subham has taken initiative and brought the German Technology called Puroo by ATB. It aims to ease the operation of the plants and keeping it simple and secure.
What is Puroo?
It is the small waste water treatment plants, simple to handle, very secure, clean and economic.
The water flows via the primary settling stage
(1) into the SBR tank
(2). The intermittent aeration takes place in the SBR tank, and that so long until the mechanical ball valve
(3) float activates the air flow pump
(4) due to the higher water level. First, through this activation, the sludge return flow takes place in several short pump strokes. Now follows the settling. With this, the sludge sinks in the SBR tank. The air lift pump is activated again and now transports the treated water out of the plant
(7). A valve
(6) integrated into the outlet differentiates between short pump strokes (= excess sludge draw-off) and longer pump operation (= clarified water draw-off). With minimum water level the air flow is again switched from the air lift pump to the pipe aerator
(5). The sequence starts again from new. The cycle is thus not controlled time-dependent but rather water level-dependent.
