It depends on the type of sealer used. Penetrating sealers can't be removed so we will stick with topical sealants. Some topicals like acrylic sealers might be dissolved with various chemical cleaners (assuming it water-based--solvent based sealers are much harder to remove chemically). If the sealer is starting to peal or delaminate then a cleaner and powerwasher may help lift the rest of the sealer off the surface. If you know what type of sealer was used, contact the manufacturer and get suggestions on removal.

I've heard of concrete sealer but don't know exactly what it is. What is it used for?
It all depends on what the concrete is used for. If it's a footing or foundation that's in direct contact with, and buried by, surrounding earth, you can use heavy duty (6 mil) poly sheeting, or glop asphalt/tar all over it. If you're talking a sidewalk, driveway, stairs, or some such visible surface with foot or vehicle traffic, you want to use a penetrating sealer---concrete sealer, or Thompson's Water Seal.
Depending on what kind of sealer you use, the concrete should be completely dry and firm enough to walk on. However, I know of at least one concrete sealer (Concrete Treat) that can be applied immediately after the concrete has been placed -- with no wait at all for curing. Check out the products as you go and see what might work best for you. See the attached link.

You can apply Trojan Masonry & Concrete Sealer which is a water based polyester sealer that penetrates and hardens the concrete. As it is not a topical sealer like acrylics or silicones, you won't get hot tire pick up or a glossy, slippery finish that easily wears away.
