Mechanical Screen
Captures solids and debris before wastewater enters the system. Models range from non-electric to fully automatic to suit each plant’s volume and wastewater characteristics.
Manufacturing & Import
Mechanical Screens / DAF Grease Traps
Start treatment right at industrial plants with a Hydrosys Pretreatment system. Mechanical screens and grease traps protect equipment and cut load on your main treatment system.
Solid waste and
grease wear out
systems early
Industrial wastewater often carries heavy loads of solid waste, suspended solids, and grease. Sent straight to treatment, they add load, raise costs, and risk clogging.
Hydrosys designs, manufactures, and imports mechanical screens and grease traps that protect the main treatment system, cut clogging at the source, and extend equipment life.
Our Systems Make sludge disposal easier to manage
Make sludge disposal easier to manage
with a Sludge Treatment System
Handle waste cake efficiently with innovations that cut volume, weight, and cost, turning liquid waste into dry, easy-to-handle cake with maximum added value.
Grease Trap
Ultra-fine micro-bubble technology removes up to 95% of grease and 90% of suspended solids before water reaches the main treatment system.

6 Mechanical Screen &
Grease Trap Solutions
Mechanical screens and grease traps designed per industry. 6 solutions built around wastewater characteristics, so you can choose what fits.
01
Mechanical Screen
(Static Screen)
Captures debris and solids before they enter the system, protecting pumps and valves, reducing clogging, and extending equipment life.
02
Rotary-Drum Fine Screen
(Rotary Screen)
Removes solids that build up on the screen, reducing clogging and keeping wastewater flowing steadily.
03
Internal-Feed Rotary Screen
(Internal Screen)
Separates solids with no odor nuisance, continuously and with automatic self-cleaning.
04
Fine Screen
An automatic screen that delivers fine screening in a single step. Continuous, quiet, and easy to maintain.
05
Micro Bubble Pump
A compact micro-bubble pump needing no auxiliary equipment, mixing air into the water in one pump to float solids out immediately.
06
Grease Trap
(DAF)
Removes up to 95% of grease in a single step and up to 90% of solids, delivering cleaner wastewater to the biological stage.

About our wastewater treatment
systems and related equipment
How does this differ from a conventional grease trap?
DAF removes 85–95% of grease and handles far larger volumes than a conventional grease trap, which manages only around 40–60%.
If the wastewater only carries solids, is DAF necessary?
No. If solids are the main issue — vegetable scraps, bones, cotton wool, branches — a screen alone (static or rotary) is enough.
How much space does a DAF system need?
Not much. It is a compact micro-bubble system that takes a fraction of the space of older designs, and it can be laid out to suit your site.
Will this alone bring water up to standard?
No — it is not the final stage. It does cut COD/BOD by 30–50% and remove grease and solids, so the main treatment system works far more easily.
Does a rotary screen need constant supervision?
No. It cleans itself automatically; you only need routine inspections.
