It has the goal to separate coarse and medium-fine solids at the inlet, avoiding thus their sedimentation in the next stages and clogging in the machinery (pumps, mixers etc.). There are several models of screens, depending on the type of plant: rotary drum, arch with brushes, arch with comb, static, cascade, disk, step, cochlea etc.
The Temperature plays a main roll for the Biomass reproduction and respiration which under takes place 36-38 Degree Celsius. It’s recommended to keep and maintain the biological oxidation system temperature below 38 degree Celsius as of textile industry has hot water drains.
Belt Press is a machine for Dewatering/De-sludge from the mixed biological and chemical solids. The system helpful for the Biological sludge wasting and disposal. The sludge, biologically conditioned, is discharged in the first draining zone, where the sludge loses much of the contained water by gravity, beginning the process of drainage.
The mix of water and sludge enter in a proper central diffuser cylinder. The sediment able solids, due the gravity, use to settle on the bottom from where, by suitable scrapers, placed on a girder anchored to the centre of the sedimentation tank and with peripheral traction, are sent to the central part of the cone and extracted by pump.
It is effective against large variety of bacteria and also penetrates into biofilm to remove it. It doesn’t damage or oxidize the RO membrane. Appearance is like Light yellow to brown liquid, so that handling will be easy. It has pH of 3 & specific gravity of 1.2 to 1.4 @ standard condition. It reduces CIP cleaning frequency.
It is based on Phosphoric acid compound with pH < 1. It prevent scale formation on the surface of RO membrane up to 2000 ppm of hardness. If dosage is beyond the stabilization limit an amorphous precipitate is obtained on surface of membrane it can be removed by normal flushing
It is based on potassium hydroxide compound with pH 12.6. It removes FOG, inorganic deposits and ester. The product to be neutralize Before cleaning
It prevent scaling formed by silica up to 500 ppm of silica. It having high pH. Compatible with all types of membranes
