Ultrafiltration of waste water - Import export

Ultrapure water has an extremely low conductivity since it has been totally desalinated. There are no ions (contamination) in ultrapure water because of the poor conductivity. Salts can be removed from water using a variety of methods. For this, Grünbeck uses our high-quality reverse osmosis installations, followed by a mixed-bed or electro-de-ionization process (EDI).

The Backwashing adjustment of the emphasis on the extraction side only works when used in pressure areas It is in accordance with the specifications of DIN EN 13443-1 and DIN 19628 and for installation in drinking water installations in accordance with DIN EN 806-2 . It protects the water pipes and the connected systems components against malfunctions and corrosion damage

Ultrafiltration of kathodic deposition paint The filtrate of the ultrafiltration is added to the immersion bath by a spray ring, which is installed directly over this bath. So, the recovery of the remaining color is possible and by separation the color particles, painting defects can be avoided. In the last spray zone, organic solvents from the ultrafiltration are washed away be demineralised water. Concentrated with these solvents, the water is leaded into the color bath. The process is a closed loop without any waste waters. The paint bath can be contaminated with pre-tretment chemicals like e.g. phosphates, chlorides, chromates. so, a part of ultrafiltrate has to be leaded out to avoid concentration of the paint bath with these chemicals. If no ultrafiltration is used, big amounts of waste waters will arise, which are difficult to dispose. Our ultrafiltration plants are customized in membrane are, retention rate and membrane type.

A clear matter: disposing of process water in an operationally safe manner After vibratory finishing, the process water contains solids and pollutants such as metals, oils and greases. To prevent these from entering the sewage system during disposal, you can clean your process water - even acidic or alkaline water - in our flocculation plants. You can then discharge the clear water into the sewage system in accordance with legal regulations. DO/GA flocculation units The PLC-controlled DO and GA flocculation plants are fully automatic solutions that purify up to 2,000 litres of process water per hour. If your daily water volume to be treated exceeds 3,000 litres, these plants are the right choice for purifying your process water. RT flocculation unit The easy-to-operate and inexpensive RT unit is suitable for you if you want to purify a daily water volume of up to 3,000 litres.
