Parason’s ETP Solutions for Industrial Wastewater Treatment

The industrial wastewater has a negative effect on the environment, and the release of the untreated wastewater can lead to the contamination of natural water bodies, harm water life, and can have serious health risks for human. Given these potential dangers it is crucial for maintaining a sustainable environment to do the industrial wastewater (effluent) treatment.

At Parason, we are committed to promoting sustainability hence our innovation of Effluent treatment plant solutions can minimize the potential dangers from industrial wastewater.

What is an Effluent Treatment Plant (ETP)?

An Effluent Treatment Plant (ETP) is a facility designed to treat wastewater generated by industrial activities. The main objective of an ETP is to remove harmful pollutants from the water, making it safe for reuse or discharge into the environment. Parason’s ETP solutions are engineered to address the unique challenges faced by industries, particularly in the pulp and paper sector.

Parason ETP Machinery

Parason offers state-of-the-art machinery for the Effluent Treatment Plant. Our solutions are crafted not only to minimize environmental impact but also to maximize your investment returns.

Our ETP machinery range includes:

Rotary Drum Screw

Dissolved Air Flotation (DAF)

Belt Filter Press

Sludge Screw Press

Fifty Filter-Micro Filtration Unit

Spray Filter Fractioning Screen

Rotary Drum Screw

Our rotary screen system is designed to efficiently separate solids and liquids, especially in high-flow conditions. This innovative system combines filtration and compacting in a single unit. It features a screen basket made from either perforated sheet or wedge wire, which serves as a reliable filter while rotating with the transport screw.

Dissolved Air Flotation (DAF)

The flotation cell is a dependable and straightforward clarifier that effectively removes both floatable and settleable solids from water suspensions, resulting in clear water. Its primary mechanism is Dissolved Air Flotation. The process begins by introducing raw water into a central distributor, where it mixes with air from an air carrier water. Air bubbles help lift the flocculated solids to the water surface, while heavier particles settle at the bottom. The clear water between the floated and settled solids is then discharged through an adjustable weir.

When combined with appropriate chemicals, the flotation cell can achieve Total Suspended Solids removal rates of 95% or higher. Additionally, it is particularly effective for fiber recovery in the pulp and paper industry.

Parason Belt Filter Press

The Parason Belt Filter Press is designed to effectively squeeze sludge for various industrial applications, including primary and secondary clarifiers and the deinking process. This press efficiently squeezes sludge from a consistency of 2-3% by adding a polyacrylamide-based flocculant, enhancing drainage to achieve a consistency of 25-28%.

Parason Sludge Dewatering Screw Press

The Sludge Dewatering Screw Press is a compact unit that combines conditioning, thickening, and dewatering functions. It operates continuously and automatically, efficiently removing moisture from sludge to achieve an outlet consistency of up to 25%. This equipment eliminates the need for a sludge thickening tank and filter press, resulting in a smaller footprint and reducing the manpower required for cleaning and discharging sludge.

Fifty Filter-Micro Filtration Unit

Treated water from the central feed drum flows downward by gravity into the filter sector. At the start of the filter cycle, the filter assembly remains stationary. Any impurities larger than the mesh opening size become trapped on the inner side of the filter's sector.

As impurities accumulate on the filter cloth, the flow of water gradually decreases, causing the water level in the drum to rise. Once the water level probe detects this rise, the filter discs begin rotating, initiating a backwash process. High-pressure backwash nozzles direct the trapped impurities toward the sludge trough.

During the backwash cycle, the water level decreases to a preset minimum level. Once this level is reached, the rotation of the unit stops. At this point, filtration resumes at maximum capacity, and the cycle repeats itself. The filtration process continues uninterrupted and continuously. Feed water contains 150-200 PPM TSS in the filter, and less than 50 PPM TSS can be achieved at the outlet of the filter.

Spray Filter Fractioning Screen

This advanced water treatment system is renowned for its effectiveness in separating fine and coarse particles. It operates straightforwardly and reliably with minimal moving parts. Water is introduced through the lower inlet pipe and directed by specialized nozzles in a distribution header to a 400-mesh fabric screen. This screen efficiently captures particles larger than 50 microns while allowing smaller ones to pass through. The screen is affixed to a rotating drum, ensuring consistent performance.

The filtration process yields precise particle separation, effectively trapping those exceeding 50 microns and enabling finer particles to pass. Maintenance is simplified by a generous access window, and the system is self-cleaning, eliminating the need for freshwater and contributing to cost savings.
