Application of Plate and Frame Filter Press in Alkaline Desulphurisation
In recent years, alkaline desulphurisation has been widely used in coal treatment and utilisation projects. At present, the sulphur foam in alkaline desulphurisation adopts the process of continuous sulphur melting in sulphur melting kettle to produce molten sulphur. The sulphur foam overflows from the regeneration tank to the foam tank, which is equipped with agitation to make the foam and clear liquid form a homogeneous suspension, and the foam is used to...

Utilisation of plate and frame filter presses in the soda ash industry
Reasons for utilising plate and frame filter presses In the soda ash production process, brine refining is required to improve product quality, reduce ammonia, salt, and carbon dioxide losses in the production process, and reduce scarring in the tower piping. Raw salt is dissolved in hot water to make saturated crude brine. In the process of removing magnesium and calcium, a slight excess of stone is added...

Influence of filter press sludge deep dewatering-PAC conditioner
A sludge incineration and disposal plant is proposed to be built in Hangzhou, where centrifugal sludge with a water content of 80% will be incinerated after deep dewatering using plate and frame. In order to improve the economic value of sludge incineration, it is very important to reduce the dry basis increment caused by the conditioner and not to reduce the calorific value of sludge in the pretreatment process, therefore, it is necessary to find a new agent instead of...
