Improve rinsing while reducing water consumption as much as 90%!

Take 10 minutes and learn how to improve rinsing while reducing water consumption as much as 90%…

Long ago, the answer to good rinsing was to simply “open the valve all the way”. However, with conservation and pollution control, we are learning to turn off the water, and recover whenever possible. But what's even better, good rinsing techniques help produce quality parts.

When two rinse tanks are connected, such that water flows from rinse number two, to rinse number one (figure 1) some beneficial math results. The dragout from rinse number one to rinse number two is re-diluted so that the total dilution is almost the multiplication of the dilution in each rinse tank.

You will use less water and get better rinsing if the dragout tank is used as the rinse and is included in the chain of counterflowing rinses.

TABLE 1 – WATER REQUIRED TO DILUTE ONE GALLON OF DRAGOUT
Dilution Ratio	One Rinse	Counterflowing Rinses
	(gal)	2	3	4	5
100:1	99	10.0	4.3	3.0	2.3
1,000:1	999	31.0	10.0	5.4	3.8
5,000:1	4,999	70.0	17.0	8.2	5.3
10,000:1	9,999	100.0	21.0	10.0	6.1
20,000:1	19,999	141.0	27.0	12.0	7.0

The Bottom Line: Any method used for dragout recovery or waste water minimization is made more practical and economical when water flow is reduced. It is always easier and cheaper to get one pound of materials from one gallon of water than to get one pound from 100 gallons. If you use counterflow rinsing (with or without sprays), you will get better rinsing, save an abundance of water and increase profits.

Lamports - Filter Cloth Replacement

When you decide to replace your filter press cloths you need to know there are three different kinds of cloths on a filter press:

• the head cloth, which is the first plate and is a single cloth with a hole in the center;
• the tail cloth, which is the last plate and is also a single cloth but with NO HOLE in the center;
• the intermediate cloths, which are all the cloths on the plates between the head and the tail. These are double cloths, with one on each side of each plate,

The hole in the center of each side is connected by a short cloth tube.

Be careful when putting the plates back into the filter press. There are two different types of plates. They are designated one button plates or three button plates. The plates can be identified by a drill hole that is about 1/4” deep, in the handle of the plate.

The one button will have one hole and the three button will have three holes. The head plate is usually a one button plate. The next plate MUST be a three button plate then a one button and so on. The filter press plate sequence is 1-3-1-3, and so on. If this order is not correct, the filter cake will not dry properly during the Blowdown process.

Reverse Osmosis Systems

Reverse Osmosis (RO) is the most efficient process available to remove dissolved minerals, bacteria, particles and organic impurities from water supplies.

So what makes a good Reverse Osmosis system?

• Expandability – System should be modular
• Liquid-filled pressure gauges – assuring pulse-free readings and long gauge life
• Line-mounted flow meters – accuracy and corrosion- free performance
• Rotary vane pumps – industry standard for trouble-free service, efficiency and corrosion resistance
• Pressure relief valves – protect rotary vane pumps from over-pressurization
• Control systems – should be adaptable to suit your specifications
• Needle valves – needed for precise flow and pressure control
• Convenient layout – all gauges, meters and controls should be mounted next to the control panel for ease of operation.
• Feedwater solenoid valve – shuts off feedwater when system is not operating.
• Low-pressure switch – protects the pump from cavitation and damage caused by inadequate inlet pressure.

What makes a great Reverse Osmosis system?

• Computerized system design – accurately projects system performance based on each application’s requirements and operation conditions.
• Premium control option – includes microprocessor-based controller for increased reliability and process control capabilities.
• Fiberglass frame – assembled with stainless steel hardware for total corrosion controls
• Stainless multistage centrifugal pumps and product pumps - for long life
• Spiral wound, thin film composite membranes – provide superior salt rejection and product flow at low operating pressures and offer excellent membrane lift.

Why you need sterile tank vents

Sterile tank vents reduce batch contamination, product loss, and spoilage. Effective sterile submicron filtration is a necessary part of any sterile process. This is especially important in consumables such as food, beverage, and pharmaceutical industries. Sterile vent filtration protects your product from submicron particle contamination and bacterial growth or transfer.

 

To reduce the possibility of contaminating your product during emptying and filling of vessels a tank vent or breather filter is essential. This filter will help maintain safe, balanced pressure during the process.

 

We've found that MicroPure's tank vents are excellent for this process. They are:

• Self-sealing PTFE membranes with a 0.2 micron retention efficiency for air and gas.
• Each Filter Membrane works independently allowing for maximum filtering capability.
• A stainless steel tension rod and parts that provides continued support upstream and downstream of the filter membrane.
• The design of Micropure Segmented Filters has been subjected to extensive testing in Europe and the United States.  

Micropure Tank Vents also have terrific Application Versatility:

• The required segmented element length and diameter are determined by your application giving each application an individualized fit.
• Unlike conventional cartridge filters, Micropure's Segmented filters can handle bi-directional flow.
• Filters allow higher flow rates than conventional filters while maintaining submicron bacterial efficiency.**
• High Temperature Tolerance

The rugged, reliable design of Micropure Segmented Filters has been subjected to extensive testing in Europe and the United States, with more than 5,000 systems installed in food-and beverage-processing applications.
