Treatment of stone wastewater
Thread Content
I would like to ask the experts: there is a stone processing plant that mainly deals with various types of marble. The wastewater generated there comes primarily from cutting processes. With current environmental regulations in place, what measures can be taken to ensure that the wastewater meets the required standards? So far, five or six ponds for natural sedimentation have been created, but the effect is not noticeable! !
Relying solely on sedimentation is not easy to operate; filter equipment such as membrane filtration or pressure filters can be considered for treatment
First, what are the environmental protection requirements, and what water quality standards need to be met? For membrane filtration, the initial investment might be a bit high; coagulation sedimentation can be used instead
I need your water quality data and discharge standards so that the advice I give can be tailored to your situation.
Floculants can be added, followed by precipitation and filtration
A cyclone can be considered! This device is a static type of equipment; it has a simple structure and low cost, and it is capable of separating solids with a significant difference in density from water.
What is needed are your environmental requirements; otherwise, it’s difficult to compare the processes
Specific improvements are made to meet the discharge standards required by the environmental protection agency. Stone processing plants typically have a high level of suspended solids in their wastewater; therefore, several dosing tanks need to be installed along the flow path through the sedimentation tank, with polyaluminum chloride being added first, followed by polyacrylamide. If possible, an additional plate and frame filter can be used to compress the sludge – the treated water can then be reused! Those who have questions can add me at 985305084qq
It is recommended to use high-density sedimentation tanks, which can achieve solid-liquid separation. If there are requirements regarding the salt content in water, it is necessary to analyze each case on a case-by-case basis.
