Hi-Consistency pulper is connected with dilution pulper. The dilution pulper has the due function of separating the plastics and other foreign material and also dilute the high consistency for stock transfer for further processing. This pulper has a 6-8 mm drilled screen plate with an impeller rotating against the screen. The impact of the impeller separates the fiber from the rejects, hence working most efficiently for fiber recovery.

Disc Filter is an optimized solution from Parason to enhance the capacity and filtrate quality by reducing freshwater consumption, save heat energy by closing the water circuit of the dewatering process. All Parason and conventional disc filters can be upgraded to these new high-quality products.

Parason High Consistency Disc Filter (HCDF) is developed for effective pulp thickening in a wide range of flow applications. The HCDF is adaptable to higher feed consistencies and supports operations of variable grades of pulp and recycled paper.

The pulp is fed into the vat through the inlet located on the side of the filter. The mat formation starts under gravity ensuring optimal dewatering. As the rotor rotates, the filtrate is drained through the channels into the outer rotor pipe under vacuum. The fiber mat is knocked off at the top which causes the pulp to fall into the pulp discharge screw that is located at the center. The rotor channels have a connected valve for separating the cloudy and clear filtrate. The filtrate can be further separated into the clear and super clear filtrate.

The Gravity Disc Thickener is a compact and virtually maintenance-free, Gravity Thickener can be adjusted according to process conditions such as throughput and inlet consistency. The pulp suspension is fed at a consistency of 0.9% to 2.5% to the inlet chamber into the vat in the same direction as disc rotation.

Thickening capacity is ensured by the number of discs installed in the center shaft. The thickener vat level and outlet consistency are controlled by thickener speed through VFD.

Our technologies continue to lead with the highest quality Dissolved Air Flotation (DAF) products and with unmatched expertise in wastewater engineering applications of DAF. Our innovative and cost effective technologies are the remedy to contaminated water sources, prevent further pollution, and recover valuable materials. Parason DAFs are providing the solution to wastewater treatment and recovery of resources.

                                    DISSOLVED AIR FLOTATION - DAF                                 

The untreated water flows into the unit in one direction as the rotating carriage travels in another direction. These two forces oppose each other and equalize to create a 'zero-velocity within the flotation zone. This causes the fine air bubbles from the ADT to attach and lift the suspended solids to the surface where the sludge blanket is formed.

The Parason Deinking Cell consists of a number of cells in series with an elliptical cross-section with a baffle extending over the entire length to a separate suspension chamber. Air (at the atmospheric pressure) and pulp stock to be deinked are introduced into the cell chamber through a specially designed injector nozzle. Flow-through nozzles generate a negative pressure that sucks in the necessary process and generates microturbulence resulting in widely ranging bubble sizes enabling efficient removal of an equally wide range of particle size.

It makes a lot of sense that a refiner disc should have uniform wear properties. Normally the variation in the wear of the refiner plates may be wavy, serrated, or flat type.

The wavy & serrated wear causes maximum fiber damage and multiple disadvantages of high power consumption, increased cost per tonne, load variations, etc. PARASON has innovated the concept of `ERP’ that is Edge Retention Property. During strenuous refining conditions, the ‘ERP’ plate has flat wear.
