Demineralization is the removal of essentially all inorganic salts. In ion exchange demineralization hydrogen Cation exchange converts dissolved salts to their corresponding acids, and basic anion exchange removes these acids.
Purpose
Removal of ionic substances
Reduction of conductivity
Control of pH
This presentation envisages on theory Of Filtration, Types of Filters, Slow Sand, Rapid Sand and Pressure Filters Including Construction, Operation, Cleaning, Operational Problems In Filters, Design criteria of Slow & Rapid Sand Filter Without Under Drainage System.
How Reverse Osmosis Water Purification Systems WorkAlisha Roy
Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. http://catalogs.indiamart.com/products/reverse-osmosis-systems.html

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

2. What is Reverse Osmosis?
• Reverse osmosis (RO) is a separation
process that uses pressure to force a
solvent through a membrane, which
retains the solute on one side and
allows the pure solvent to pass to the
other side.
3. Advantages of RO
• Improves taste, odor and appearance
• Highly effective purification process
remove the pollutants
• Consumes no energy
4. Advantages of RO
• Flushes away pollutants, does not
collect them
• Easy to keep clean
• Low production cost
