Process advantages

1) High quality of produced water: SS in produced water is below 0.1ppm, conductivity is <50μs / cm, and water quality is stable;

2) Land saving: Membrane treatment of titanium dioxide wastewater replaces large-scale land occupation facilities such as sedimentation tanks, and the construction area is greatly reduced;

3) Investment savings: High recovery rate of titanium dioxide, recycling of production water, a budget of 30,000 tons of titanium dioxide enterprises recovers titanium dioxide over 4 million yuan per year, and saves water resources over 2 million yuan;

4) Long service life: The ceramic membrane is not affected by acid, alkali, high temperature, high pressure, etc., and the service life is more than 5 years;

5) Simple operation: Short technical process and few control points can realize DCS automatic control.

Membrane equipment

膜法成套设备

Four core technologies

1. Acid-resistant titanium dioxide particle concentrated film

Using special industrial separation membrane, customized according to the size of titanium dioxide particles, it can stably recover and concentrate all titanium dioxide, with a rejection rate of 100%

2.Acid-resistant metal ion separation membrane

Use special separation membrane to separate metal ions, get clean acid and concentrate metal ions without affecting the acid concentration for recycling

3. Dilute acid concentrated film

The special acid concentration membrane is used to further concentrate the clean acid absorption to obtain a clean acid with a higher concentration, and at the same time, it produces excellent recycled water. Prepares for further acid concentration and greatly reduces the cost of direct evaporation and concentration of dilute acid

4.MVR evaporation concentration

Adopt German special steam compression technology to achieve low temperature negative pressure evaporation of sewage, and its energy consumption is 1/3 of traditional evaporation equipment. Occupies 1/5 of traditional equipment
