Maintaining the biologic balance and a healthy nature require the reduction of the contraries in the effluent. Phosphates are therefore reduced in the biologic treatment step in purification plants by means of bacteria (biologic phosphate elimination).
For observing even the high demands for waste water values in the various steps of purification plants, an additional phosphate precipitation step with metallic salts such as ferric-III-chloride or aluminium sulphate is executed.
In the „simultaneous precipitation“ the precipator is dosed in the input of the activated sludge tanks. The phosphates combine with the metallic salts to insolvable particles and can thus be separated from the effluent without any problems.
ProMinent has decades of experience in designing and constructing plants for chemical phosphate elimination.
Essential plant components are:
- General Construction Approved reservoirs for storing fluid metallic salts
- Metering pumps for exact dosing
- Control devices for avoiding -under or over dosing
For the flocculation of municipal effluents, ProMinent offers a large range of polyelectrolyte mixing stations ready for mixing and dosing flocculation additives.
For the optimization of the oxygen input into the activated sludge tanks (biological step) of purification plants, we offer tailor-made sensors as well as measuring and control technology for the measurement of the dissolved oxygen.
For reliable pH correction, especially for industrial effluents, we offer both complete neutralization plants for fully automated pH control and individual components for this application. |
