What is Rinse water?
Water is an important part of the cleaning process. Used as a medium for cleaning agents and as a brightener, it provides mechanical energy and heat during the cleaning process. Tap water normally contains several elements that, when combined with heat, can cause staining and corrosion on dishes. They can also damage washers, shorten their life and increase maintenance costs. Water contamination can interfere with cleaning agents. Therefore, softened or purified water is generally recommended for the wash step of the process. The last step of any washing process generates rinse water.
For a high-quality surface finish, you need a first-class critical cleaning process. It is important to remove oils, metalworking fluids, and fluids that are used to avoid corrosion or other surface damage during storage.The cleaning process is only as good as the rinsing step. Inadequate or ineffective washing can be costly.
Use of Rinse water in Glass Industry
Rinse water is used in Glass industry for washing glasses. This process requires demineralised rinse water and nothing else. The following steps are followed in Glass washing Industry-
Demineralized rinse water: The water is first pre-treated in an ion exchanger softening system and then demineralized using reverse osmosis, a chemical-free technology. The demineralization process ensures that there are no stains, dirt or residue and significantly improves the adhesion of the PVB film.
Water Savings - A properly designed recycling process reduces the need for fresh water. The rinse water is reused / circulated through a special double filter, which is a combined gravel and activated carbon filter. The filter removes cutting fluid, debris, and excess particles, including broken glass, intermediates, and other contaminants.
Storage tank and booster pump: Make-up water and recycle water are collected in a storage tank. The treated water from the tank is fed to the rinse zones through a pump built into the skid. Many times, the reuse or recirculation of rinse water is a great economic benefit as it reduces water consumption. Reuse is particularly beneficial if the rinse water becomes contaminated during the process and therefore wastewater treatment is required prior to discharge.
Methods used to get the required demineralised rinse water
Pressure Filter
A pressure filter is a closed tank that contains one or a combination of filter media to remove one or more contaminants. For the removal of iron, manganese, ammonium and aggressiveness in sanitary works, companies and private homes, we have more than ten different filter materials from our suppliers.
Regardless of whether it is drinking water or for commercial or industrial use, the water must be treated before it reaches the required quality. The complexity of the treatment clearly depends on the quality of the water supply and the end application.
In most cases, water reuse requires the following technologies.
Water Softening Systems for Softening
Water Softening Systems are used to reduce calcium and magnesium in water through cation exchangers. Calcium and magnesium are exchanged for sodium through ion exchange.
Reverse Osmosis Systems High Quality Demineralized Water
Reverse Osmosis (RO) systems are used to produce demineralized water without the use of chemicals. In addition, reverse osmosis systems remove pyrogens and microorganisms, as well as up to 90% of organic substances. Softened water is used for steam boiler systems, district heating plants, laundries, cooling towers, dishwashing processes, washing, dishwashing, etc. with a growing demand for demineralized water.
Reverse Osmosis System
UV Disinfection Systems UV light can efficiently reduce microbiological growth in water. Ultraviolet radiation with a wavelength of 254 nanometres kills bacteria, viruses, algae and fungi by destroying the DNA of microorganisms. Ultraviolet light disinfection can be used in almost all types of water.
