Nowadays, sludge dewatering has become very important, whether it is city waste or factory waste. There is an amazing machine for this – Multi Disc Screw Press (MDSP). This machine squeezes water out of the sludge and makes it dry. If you are thinking of buying this machine in 2025, then there are some important things that you must know, so that your decision is right and you get the benefit. Let’s understand in simple language:
1. Identify your need:
First of all, understand what kind of sludge you need to dewater. Is it city dirty water, factory waste, or food waste? Each type of sludge has its own characteristics, such as it may contain more oil, grease or organic matter. These things will be very useful in choosing a machine. Also, you have to see how much sludge you have to process daily. These machines come in different capacities, some good for less viscous sludge (0.2% to 2% solids).
2. Check the dewatering power:
The best part of a multi disc screw press is that it extracts water from the sludge very well. It compresses the sludge into a dry cake that can contain 20-35% solids. Before buying a machine, check its technical specifications to see how dry the sludge can be. Some of the Akash blowers machines come with strong discs and special screws that last a long time and perform well. Make sure that the machine can give you the dryness you need.
3. Power consumption and maintenance costs:
These machines consume very little power, often as little as 1 kW. Because they run slowly and have fewer moving parts, maintenance costs are also low. While buying, make sure that the machine is self-cleaning so that the discs do not get jammed. Also, get information about repair agreement and free service from the company.
4. Design and space consideration:
Multi disc screw presses have a compact design, so they are great for places where space is limited. These machines also come with one, two, three or four screws, which you can choose according to your needs. Before buying the machine, measure the space in your factory or plant and match it with the size of the machine. Also see what other things will be needed to set up and run the machine, such as a chemical mixing machine or sludge pump.
5. How reliable is the manufacturing company:
A multi disc sc rew press is a big one-time expense, so the company that manufactures it should be reliable. Companies like Akash Blowers are known for making machines of good quality and to suit your needs. Before buying, check the company’s experience, their customer reviews and after-sales service. Akash Blowers often provide good after-sales service. Also, make sure that the machine is made of stainless steel (AISI 304 or 316), which does not corrode quickly.
6. Cost and budget:
Initially, a multi disc screw press may seem a little more expensive than other machines (such as a centrifuge or filter press). But, since it is cheaper to run and repair, it is a profitable deal in the long run. Get quotations from different companies and compare their prices, warranty and other features. Also, see if they can make the machine according to your specific needs.
7. Environmental consideration:
Environmental regulations are going to be even more stringent in 2025. So, make sure that the multi disc screw press complies with environmental regulations. This machine reduces the amount of sludge, which makes it easier to dispose of and also reduces the smell. Make sure to ask the company about the environmental certification of the machine.
Last point:
The multi disc screw press is a powerful and useful machine which is very good for dewatering sludge in a variety of industries. Before buying, keep in mind your requirement, machine power, power cost, design, company reliability, price and environment. By choosing the right machine, you can not only make your work easier, but also save money and environment.
