LG Sonic Algae Control. LG Sound is the leading international provider of innovative ultrasound systems that reduce and control the formation of algae, biofilm and some other micro-organisms in all situations where water is stored. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these.

About Us

Image

LG Sound is a leading international manufacturer of ultrasonic algae control units founded in the Netherlands since 1999.

LG Sound is an established developer of the LG Sonic technology to safely control algae, cyanobacteria and biofilm. Our objective has always been to reduce or eliminate harmful chemicals in our environment. Therefore we have developed a chemical free technology that controls algae and biofilm without disturbing the natural balance within water ecosystems.
In the course of the last decade, over 10.000 LG Sonic products have been successfully installed in different applications such as natural water surfaces and industrial water that suffered from algae or biofilm problems. With a team of multidisciplinary experts, LG Sound manages to keep at the edge of the market by holding worldwide approved certificates, patents and know-how for the algae control ultrasonic technology under the trademark LG Sonic®.
Offering a long-term environmentally friendly and efficient ultrasonic algae control solution, we have rapidly improved our competitiveness and today we are proudly holding the leading position on the worldwide market. The LG Sound team has the expertise to offer project based assistance, customized products and services to a wide array of clients.

With a great understanding of all biological and chemical processes in watery ecosystems, LG Sound aims to keep on innovating their product to meet their customer’s needs. Besides that, it offers biological, chemical and water quality support to all of their customers before and after sales.

Innovation Oriented

By constantly innovating our product range and investing in new developments we aim to keep high quality standards so we can always meet our clients expectations. In order to reach these goals, LG Sound has a strong focus on research and innovation, where lies the basis for their three product lines, that are regularly being updated to the latest state-of-the-art. Through cooperation in several national and EU funded research projects, LG Sound has innovated and developed the unique and patented MPC-Buoy. This technology uses a combination of water quality monitoring and precise ultrasonic programs to selectively control harmful algae blooms. Through this development, a new market was created to which at present no product is available.

 

Distribution network

With over 10 years of experience as an international producer of ultrasonic algae and biofilm control products, LG Sound has grown to become an international company with sales in 52 different countries and a worldwide distributor network.
We believe quality and expertise is the foundation of all our activities and our entire production and distribution process is built around this. This allows us to offer extended guarantees and to always comply with the highest quality standards.
LG Sound believes in running the company in an efficient and professional manner, improving the supply flow and adding value to their partners and distributors.

CSA Standard for Power Supplies with Extra-Low-Voltage Class 2 Output, CAN/CSA-C22.2 No.223-M91,Second edition, updated September 2009

NSF/ANSI Standard 61

NSF/ANSI Standard 61 – Drinking Water System Components was published in 1988 to establish minimum requirements for the control of potential adverse human health effects from products that contact drinking water.

NSF/ANSI Standard 61 includes criteria for testing and evaluating products to ensure they do not leach contaminants into the water that would be a health concern. These contaminants include those regulated by the United States Environmental Protection Agency (USEPA) and Health Canada, as well as any other non-regulated compounds that may be of concern.

On the contrary of our competitors, all products from the LG Sonic line can be provided NSF/ANSI Standard 61 compliant.

Golf Course Pond

Controls algae in golf course ponds without expensive chemical treatments or time consuming manual labor.
Golf courses should be maintained often and kept in perfect condition to offer golfers an optimal golf experience. A part of the golf course are the ponds on this area. Water in these ponds is often stagnant and thus sensitive to algal growth. Algae in a golf course pond make the water look unappealing and thereby reduce the total impression of the golf course itself. Furthermore maintaining these ponds can be a tiresome task because chemicals are not desirable and other water treatment methods are often cumbersome or just not sufficient

Reduce Biofilm Formation

In many industrial or professional applications where water is being stored, biofilm may grow. The growth of biofilm can damage the installations and reduce efficiency of the circuit. A biofilm can grow certain substrates which can be found in water.
When temperatures are high, for example in cooling towers, a matrix of different micro-  organisms such as bacteria, fungi, algae can grow very rapidly causing the formation of a biofilm on certain surfaces submerge in water. During the formation of this biofilm, certain micro organisms starts producing extra cellular polymeric substances (EPS) which reinforce the biofilm structure.

Algae Control in Drinking Water Treatment Plant

LG Sonic algae control products control and prevent growth of cyanobacteria, biofilm and filamentous bacteria in drinking water tanks. Cyanobacteria and filamentous bacteria can produce toxins, geosmins and MIB which give a bad taste and smell to the water or potentially cause diseases. With the presence of organic compounds to the water like algae and biofilm, chlorination often results in the formation of THM’s.

LG Sonic controls the formation of these compounds without chemicals preventing problems with the taste of the water and optimizing the water treatment process.

How does this work ?

Image

The LG Sonic® solution consists of different devices, which are all made to fit it’s own purpose. Although all LG Sonic® devices have different strengths and are made for different appliances, the technique relies on the same basis.  

The ultrasound waves are produced in our control box (green). Our LG Sonic® transducer (black) emits sound waves (red) through the water in a radius of nearly 180°. Algae, within the range of the transducer, will start oscillating at the frequencies of the sound waves. When brought in resonance an algal cell will not be able to sustain some compartments within the cell, these effected compartments can damage or even rupture, causing severe stress to the algal cell. The exact reaction of an algal cell to ultrasound depends on the type of algae. A very common differentiation between algae is between green algae and blue-green algae, also known as cyanobacteria.

Image

Green algae share many characteristics with plant cells. As in plants, green algae posses a vacuole surrounded by a tonoplast, a cell membrane attached to a cell wall and chlorophyll, in charge of photosynthesis. As an effect of ultrasound, the tonoplast of green algae can rupture, releasing the contents of the vacuole to the inner cell. Besides this, the adhesion of the cell membrane and the cell wall can damage.

Blue-green algae are in fact one of the oldest bacteria. These bacteria share some characteristics with a plant cell as well. For example, the capability to produce energy by absorbing light, called photosynthesis. Blue-green algae are capable of travelling through the water vertically due to their possession of gas-vesicles. The ultrasound waves from the LG Sonic® rupture these gas vesicles, making the blue-green algae sink to the bottom and possibly die by lack of (sun)light.
